Urgh, my parent mapping series can't come be merged fast enough it
seems!

Sorry, I'm not familiar with the context. Something I should incorporate?

I think we should make this common to the qcom_cc_desc now. Can you
throw in an optional list of clk_hw pointers that also get registered as
its own patch and update the existing drivers that are all doing this?

Yeah, can do.
